It's difficult to argue objectivity with subjective-minded fanboys, isn't it? Both you and Ghostbuster have hit the nail right on the head with your explanations, but at this point, you might as well be talking to your living room wall!
@ Gosh, read Accord99's post and stop running processor intensive applications while trying to do anything else on an obviously choked laptop. At best stop comparing a dualcore to a quadcore; please do me a favor and stop that. It's retarded - 4 threads will always trump two threads when executing more than two threads simultaneously; especially if clocks are about the same. Why I'm I even having to say this?
@ The Rest: This thread is very late. Responsiveness aka smoothness

will always scale with the number of threads a cpu is able to execute simultaneously, eg.
On Intel:
PIII - 1 single thread
P4 HT - 2 threads
C2D - 2 threads
C2Q - 4 threads
Ci7 HT - 8 threads
It is simple, in the extreme multi-tasking environment, Ci7 blows everything out of the water. That is your responsiveness, or smoothness.
It's funny, fanboys comparing dualcores with quads and so on. This thread is useless, and needs to be closed.
Edit: @ roofsniper, do yourself a favor and stop posting in this thread; you have no idea what you're talking about and your spamming the thread like there's no tomorrow; I gave up counting your useless posts; to top that, you're showing a lot of attitude too, what a combination? At least allow people who actually buy and use cpus on both platforms to post their experiences. I'm tired of reading your 'nothings' already.

Out.
